If you flip 2, or turn it upside down, it becomes 5.
So, 2 to the power flipped 2, that is 5, is equal to 32.....:D

Yes, you can make 11 using only four 2s by using the following mathematical expression: (2 + 2) x (2 + 2) = 4 x 4 = 16. Then, subtract (2/2) to get 16 - 1 = 15. Finally, take the square root of 15 to get √15 ≈ 3.87, which is close to 4. Therefore, using four 2s, you can approximate 11 by following these steps.
22 + 22 - 2 = 42
22/2 - 2
22/2 *2/2
